I saw the ATOH episode where Richard helped a homeowner install a dual flush retrofit kit (Hydroright Dual Flush Retrofit + Hydroclean Fill Valve). I did the same in one of my bathrooms and it works like a charm.

I want to do it for my other bathroom, but all the faucets and other hardware there are in gold finish. I tried looking online for a dual-flush retrofit kit with a gold actuator (i.e. the part that is outside the tank, with the two buttons) - the Hydroright has a chrome knob - but could not find one. Would any of you know of options for me?

I wrote to the manufacturer, and apparently they make a white button. They offered to ship it to me. Without seeing the white button, I am unable to visualize if it would be better than just using the chrome button (or not doing anything at all). But I thought it would be useful for others to know that even though they don't advertise it, they do manufacture a white button.
